To all whom it may concern: j

Be it known that I, ADOLPH Po'rnnvrN, a citizen of the United States,and resident of Brooklyn, in the county of Kings and State of New York,have invented certain new Applying Paste to Labels, &c., of which thefollowing is a specification.

This invention relates to a machine for applying adhesive substance tolabels or the like; my objectherein bein to provide an apparatus ofsimple and e cient construction and operation whereby the uniformapplication of the adhesive substance to the lower surface of the labelsshall be expeditiously effected, and the removal of the labels from themachine facilitated. i

Accordingly my invention comprises various novel features ofconstruction and combinations of parts, which will be hereinafterdescribed and claimed.

In the drawings-Figure 1 is a front elevat-ion of a machine embodying myinvention. Fig. 2 is a plan thereof, with certain parts broken away.Fig. 3 is an end view, with the driving gear partially broken away. Fig.4 isa transverse vertical section, as on the line 4-4 of Fig. 1, showinga label as passing through and from the machine. 4

1 designates a suit-able receptacle adapted to contain the adhesivesubstance in liquid tstate. This receptacle is provided with0ppositely-inclined cover plates 2, 3, between and above which extends agum or paste 'aplplying roll 4 which is mounted to rotate within thet-ank and carry upwardy therefrom-the liquid contents. The roll isherein shown as provided with trunnions which are removably seated inslots in the ends of the receptacle, one of the trunnions beingconveniently equipped with an ordinary crank handle` 5 to facilitate theoperation of rotating theroll.

6 is a scraper or doctor blade to regulate the thickness of gum or pasteon the roller. This blade is adjustably mounted on posts 7 rising fromthe bottom of the receptacle, 'and is provided with depending lugs towhich are htted adjusting screws 8 seated in ,the forward wall of thetank. Screw and slot connections 9 between the blade and the respectiveposts afford a means t'o secure the 10., 11 are two rollers which arerotatably mounted adjacent to and inparallelism with the periphery ofthet roll 4, and are respectively provided with ,pinions 12, 13 whichmesh with a spur wheel 14 on a trunnion of the roll, whereby when thelatter is rotated the two rollers are concurrently actuated therewith.The forward roller 10,. which has its bearings in the end walls of thetank, extends adjacent to the inner or rearward edge of the forwardcover plate 2 in a'inanner to engage the leading edge of the sheet 0rstrip and feed it to and upon the periphery of the roll 4. The roller'll-is mounted above and in rear of the roller 10 and has its bearings invertically-adjustable slides 15 in the ends of the tank, whereby theroller 11 is adjustable toward and from the roll 4.

rThese slides are fitted to vertical ways in the end walls, and arevertically adjustable therein by means of set-screws 16 extendingthrough suitably disposed brackets on the receptacle. positions ofadjustment by means of screws 17 passing through slots 18 in the slidesand into the contiguous end walls.

As indicated in Fig. 4, a label (Il) when introduced to the ymachinepasses from the roller A10 to the roller 11, and in its passage contactstangentially or substantially so with the periphery of the Aroll,thereby insuring the uniform-and efficient application of the adhesivesubstance to and throughout the under surface of the label. By adjustingthe roller 11 toward or from the roll 4 I am enabled to com ensate to anicety for labels of varying thidknesses, to insure their efficienttangential Contact with the roll and thus avoidundue pressure of theroller 11 upon the/sheets. The roller 11, as will be observed from theforegoing, acts as aholding roller for maintaining the labels in contactwith the roll 4, while the roller 10 serves to feed the labels to saidroll 4 and roller 11.

19 is a series of independently-movable spaced fingers which are adaptedto bear with slight pressure upon the top of the roll 4 and immediatelyin rear of the roller" 11 in a manner to present to the leading ends ofthe label a row of 11p-standing members 195' which deflect the labelupwardly and forwardly from the roll as indicated in Fig. 4. Thesefingers are provided at their rearward ends with bosses which areloosely mounted on a rod 2O supported in and between the 'Ihe slides aresecured in their j label, and asthe fingers each other and areindependently movable,

`-their'v action is not suiclentto impair the uniformity of the gummedsurface of the label. The fingers may be adjusted along ranged in rearof said rol substance to labels,

apparatus with the gummed face up.

theshaft to accommodate labels of different widths, and moreover if oneor more of the fingers should become bent or broken, it or they may bereadily removed and another orothers substitutedtherefor.-

v The action of the up-standing members 19 is to deflect, as stated, thegummed labelslup'- wardly and forwardly from the adhesiveapplying rollafter .application of the adhesive substance to -the labels, whereby thelabels are `delivered toward the frontof the 4B reason of this oneattendant is enabledV tg feed'the labels, take them off,`and inspect thegummed surface.
